Amazon has just launched new SES services a couple of hours ago!
According to AWS…
Amazon Simple Email Service (Amazon SES) is a highly scalable and cost-effective bulk and transactional email-sending service for businesses and developers. Amazon SES eliminates the complexity and expense of building an in-house email solution or licensing, installing, and operating a third-party email service. The service integrates with other AWS services, making it easy to send emails from applications being hosted on services such as Amazon EC2. With Amazon SES there is no long-term commitment, minimum spend or negotiation required – businesses can utilize a free usage tier and after that enjoy low fees for the number of emails sent plus data transfer fees.
